One thing that you may want to consider doing is to change the following setting. Open Agenda Fusion and tap on the Fusion Icon (to the right of New). From Global Options change "Enable Exit Button" from "Yes" to "No". Once you start Agenda Fusion it will continue to run in the background even if you switch to other applications. When you switch back to Agenda Fusion it should open immediately. ---- Also be sure that Agenda Fusion is installed in main memory and not on a memory card.-- Possibly limit your calendar data, if you have a large amount of Calendar and/or Task data that is being synchronized from your desktop, you can open ActiveSync settings on your desktop and choose a more limited time frame of data to send to the device, for example, instead of sending ALL Calendar data to your device, choose maybe the past 2 weeks and 12 future weeks. Find this option in ActiveSync by double clicking on Calendar, then Tasks to find the settings.
